An enclosure is described for housing a personal computer. The natural convection system of the present invention for dissipating heat generated by the electronic components of a personal computer consists of a housing defining a cavity containing the electronic components. The major heat-producing components, such as the power supply of the computer and power transistors, are positioned at the top front of the cavity. The components are attached to a heat sink. A typical computer has a master printed circuit board. Additional printed circuit boards are plugged into the master printed circuit board. Further additional printed circuit boards may be added at any time to enhance the functionality of the computer. Therefore, plugging in additional printed circuit boards should be a simple operation. In the present invention, the master printed circuit board is attached to a side in the rear of the cavity. Other printed circuit boards are attached vertically and perpendicularly to the master printed circuit board. An access panel above the printed circuit boards opens to allow easy access to the printed circuit boards ends with connectors and room for cable connectors.
